So, in this episode they declare that O'Brien is a Chief Petty Officer. Not a Lieutenant, then, like Riker called him in "Where Silence has Lease"?

Great Moment :

It's nice to see that the Jem'Hadar aren't quite the empty machines we've been told they are.

Plotline

Marooned on a planet in the Gamma Quadrant, Bashir and O'Brien find a group of rebel Jem'Hadar. Their leader was stranded on the planet some time ago without his supply of Ketracel White, and suffered no ill effects. Believing that something about the planet prevents the withdrawal from the drug, he has brought his men here to escape the Founders. But as the effects of White deprivation grip the rest of his men, the Jem'Hadar begin to fall apart - and Bashir must decide whether to help his enemy or abandon his principles.
